To determine which set of numbers are consecutive, we need to compare the numbers sequentially to see if they increase by 1 each time. Here are the options provided:
-
1,23,45,345 , 1,23,45,237 , 1,23,55,221 , 1,37,29,200These numbers do not form a sequence of consecutive numbers.
-
1,23,45,345 , 1,23,45,346 , 1,23,45,347 , 1,23,45,348These numbers form a sequence of consecutive numbers, as each number increases by 1 from the previous number.
-
1,15,15,345 , 1,23,45,237 , 1,23,45,221 , 1,17,19,200These numbers do not form a sequence of consecutive numbers.

Aditi Sharma answered |
When a given number is rounded off to the nearest ten thousand, check if the digit at the thousands place is more than or equal to 5.
If the number is more than 5, add 1 to the rounding digit and replace all the digits to its right with 0.
Hence, when the number 19,73,19,371 is rounded off to the nearest ten thousand, we get 19,73,20,000.
If the number is more than 5, add 1 to the rounding digit and replace all the digits to its right with 0.

Aditi Sharma answered |
Step 1: Count the number of digits in each number. 1000 and 3222 has 4 digits whereas 111 and 225 has three digits.
Step 2: The number with less number of digits < The numbers with more number of digits
So, options b and d are not the required options
Step 3: Compare 111 and 225
Compare the hundreds digits. The hundreds digit in 111 is 1.
The hundreds digit in 225 is 2.
Since 1 < 2, 111 < 225 .
Step 2: The number with less number of digits < The numbers with more number of digits
So, options b and d are not the required options
Step 3: Compare 111 and 225
Compare the hundreds digits. The hundreds digit in 111 is 1.
The hundreds digit in 225 is 2.
Since 1 < 2, 111 < 225 .

Subset Academy answered |
Correct answer (b) In this series, the numbers are arranged in ascending order from the smallest to the largest, using the less than ("<") sign to indicate that each number is smaller than the next. Here's the explanation for the comparisons:
654321 < 876543: This indicates that 654321 is smaller than 876543.
876543 < 888888: This shows that 876543 is smaller than 888888.
888888 < 987654: This means 888888 is smaller than 987654.
987654 < 999999: This indicates that 987654 is smaller than 999999.
So, the entire sequence shows a progression from the smallest number, 654321, to the largest, 999999.
654321 < 876543: This indicates that 654321 is smaller than 876543.
876543 < 888888: This shows that 876543 is smaller than 888888.
888888 < 987654: This means 888888 is smaller than 987654.
987654 < 999999: This indicates that 987654 is smaller than 999999.
So, the entire sequence shows a progression from the smallest number, 654321, to the largest, 999999.

Gunjan Lakhani answered |
1 crore = 10 lakh.
Now, for 7000 lakh:
7000 lakh = 7000 × 1,00,000 = 70,00,00,000
We know that 1 crore = 1,00,00,000. So, to convert 70,00,00,000 into crores:
70,00,00,000 / 1,00,00,000 = 70 crores.
70,00,00,000 / 1,00,00,000 = 70 crores.
Therefore, 7000 lakh = 70 crores.
So the correct answer is: (D) 70 crores.

Vaishnavi Sharma answered |
1 crore = 10 million
To understand why 1 crore is equal to 10 million, we need to understand the number system used in India and other parts of the world.
In the Indian number system, numbers are grouped in sets of two digits. The first set is known as "ones," the second set is known as "tens," the third set is known as "hundreds," and so on.
1 crore is a term used in the Indian number system to represent ten million. It is written as 1 followed by 7 zeros (10,000,000). Let's break it down further:
1 crore = 1,00,00,000
Here, each comma separates a set of two digits. The rightmost two digits represent the "ones" place, the next two digits represent the "tens" place, the next two digits represent the "hundreds" place, and so on.
So in the case of 1 crore, we have:
- 1 in the "crores" place (10 million)
- 0 in the "lakhs" place (0)
- 0 in the "thousands" place (0)
- 0 in the "hundreds" place (0)
- 0 in the "tens" place (0)
- 0 in the "ones" place (0)
Converting 1 crore to lakhs
To convert 1 crore to lakhs, we need to understand that 1 crore is equal to 100 lakhs. This is because 1 crore is equal to 10 million, and 1 million is equal to 10 lakhs.
Therefore, 1 crore = 100 lakhs
Answer: Option B - Ten
To understand why 1 crore is equal to 10 million, we need to understand the number system used in India and other parts of the world.
In the Indian number system, numbers are grouped in sets of two digits. The first set is known as "ones," the second set is known as "tens," the third set is known as "hundreds," and so on.

So in the case of 1 crore, we have:
- 1 in the "crores" place (10 million)
- 0 in the "lakhs" place (0)
- 0 in the "thousands" place (0)
- 0 in the "hundreds" place (0)
- 0 in the "tens" place (0)
- 0 in the "ones" place (0)
Converting 1 crore to lakhs
To convert 1 crore to lakhs, we need to understand that 1 crore is equal to 100 lakhs. This is because 1 crore is equal to 10 million, and 1 million is equal to 10 lakhs.
Therefore, 1 crore = 100 lakhs
